More than 80 percent of
Puerto Rico was once again left without power after a main north-south transmission line failed.

According to the Puerto Rico Electric Power Authority (PREPA), the island was left with only 18 percent power generation on Thursday. The capital San Juan and other major cities were plunged back into darkness.

As Vox
noted, the blackout was another reminder of the island's painstaking recovery fifty days after Hurricane Maria struck. One resident said it was "hard not to feel discouraged" and called the massive power failure "one step forward and three steps back."

Incidentally, the 230-kilovolt transmission line was previously repaired by the controversial Montana energy firm
Whitefish Energy, whose no-bid $300 million contract to fix the U.S. territory's power grid is under FBI investigation.

Resident Marianne Sanchez wrote on Instagram: "Sad to report that today, the little power that was already restored … collapsed. Once again the whole island is without power. Although it is expected to be restored late in the evening or tomorrow, this is a not too friendly reminder of how fragile our power system is."

The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.

Climate change has been called the biggest challenge of our time. Last year, scientists with the United Nations said we basically have 12 years to limit global warming to 1.5ºC to avoid planetary catastrophe.

Most Europeans know the great tit as an adorable, likeable yellow-and-black songbird that shows up to their feeders in the winter. But there may be one thing they don't know. That cute, fluffy bird can be a relentless killer.

The great tit's aggression can emerge in gruesome ways when it feels threatened by the pied flycatcher, a bird that spends most of the year in Africa, but migrates to Europe in the spring to breed. When flycatchers arrive at their European breeding grounds, they head for great tit territory, knowing that great tits—being year-round European residents—know the best nesting sites.

Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.

Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Organizers said 35,000 people marched through the streets of the German capital on Saturday to say they're "fed up" with industrial agriculture and call for a transformation to a system that instead supports the welfare of the environment, animals and rural farmers.

The explosion occurred in a field in the municipality of Tlahuelilpan as people rushed to gather fuel from the pipeline, which had been ruptured by suspected thieves. Many were covered in oil before a fireball shot into the air.
